METHOD OF SEPARATELY WORKING HEEL PORTIONS ONTO STOCKINGS HerbertDietrich, Meinersdorf I. E., Germany Application November 2, 1937,Serial No. 172,440 In Germany November 5, 1936 1 Claim.

This invention relates to a method of working the heel portionsseparately ontoa stocking.

It is known to produce stockings in one operations without the heelportions and to work the 5 latter onto the high heel portions in asubsequent operation, usually on a separate machine. According to thismethod, the high .heel portions are separated from the sole portions andtransferred to the machine working on the heel portions. The innerlongitudinal edge of the heel portions is then united with the soleportions by a seam later on.

To avoid the formation of seams in such stockings it has further beenproposed to transfer also the sole portions to the machine working onthe heel portions and to arrange them inside near the latter. During theworking of the heel portions the sole portions are then hung overoutwardly to the extent of one needle after the production of a heelcourse, so that the sole portions, corresponding to the production ofthe heel portions, are worked together with the inner longitudinal edgesthereof.

Compared with the known art, the invention is characterized by thefeature that the heel portions in their entirety are continually hungover inwardly during their production by means of narrowers in suchmanner that the meshes of their inner edges gradually pass to theneedles 30 holding the sole portions and are knocked over with them.

This method affords the advantage that the narrowers pierce the meshesto be hung over only once, as always only a newly formed course of theheel portions is hung over in contradistinction to the old method whichrequires for instance piercing of the inner meshes of the sole portionsto the extent of the number of courses contained in the heel portions,whereby the transfer points of the sole portions are subjected toexcessive strain.

When stockings with their heel portions are worked in a singleoperation, it is known to unite the inner longitudinal edges of the heelportions head in the machine for carrying out the new method of twoparts corresponding to the width of the high heel portions, which aredisplaced inwardly according to the extent of the putting back of theheel portions, so that the needles holding the initial edges of the soleportions are gradually pressed.

By way of example, the invention is illustrated in the accompanyingdrawing, in which Figure 1 showsthe transfer of the unfinished stockingto I the machine working on the heel portions Fig. 2 shows the workingon the heel portions; Fig. 3 is a diagrammatic front view of theknitting tools of a section of a heel working machine; and Fig. 4, adetail view of the section.

Referring to the drawing, the stocking consisting of the leg and instepwithout the heel portions is cut at the point of contact of the highheel and sole portions on both sides to separate the high heel from thesole portions. The high heel portions l are then transferred in knownmanner to the needles 2 of the machine working on the heel portions andalso, according to the invention, the initial edges of the sole portions3. These initial edges are transferred to the needles positioned insidenear the needles which carry the end courses of the high heel portionsI. The sole portions 3 are, for this purpose turned over inwardly, asindicated in Fig. 1. Then the heel portions 4 are worked onto the highheel portions l in such manner that the heel portions 4 during theirproduction are in their entirety continually hung over inwardly by meansof narrowers. After a course of the heel portions 4 has been worked thelatter are put back to the extent of one needle, so that always theinnermost mesh of the heel courses is placed on the adjacent needleholding the sole portions, on both sides of the goods, whereupon theseneedles are knocked over also. In this manner the heel portions areunited with the sole portions during their production, .as shown in Fig.2. It is of course possible to put back the heel portions only in everyother course to the extent of two needles.

To permit successive knocking over of the v needles holding the initialedges of the sole portions 3 the machine producing the heel portionsmust be specially equipped by forming for instance the, presser bar ofeach section of two parts corresponding to the width of the high heelportions I. These two portions of the presser bar are provided on themachine independently of the sinker head and are displaceable in thelongitudinal direction of the machine. During production of theheelportions 4 the twomeinbers of the presser bar are simply displacedinwardly corresponding to the inward motion of the heel portions,whereby always those needles of the sole portions are pressed also whichhave received a mesh from the heel portions. The same end can beattained by forming the sinker head of each section of two parts havingthe width mentioned and inwardly displacing these two parts duringworking of the heel portions according to their inward displacement.This affords the advantage that the presser bar need not be separatedfrom the sinker head which might be of the usual type. Fig. 3 shows aheel working machine of this kind, in which 5 is the needle bar, 6desginates the knocking over bits and the sinker head comprises the twoparts I which can be moved back together with their presser bar 8.

In the meshes of the initial edges of the sole portions 3 the needlesconcerned of the bar 5 move idly up and down during production of theheel portions 4, unless these meshes are knocked over by the recedingmotion of the parts I of the sinker head. If these meshes of the soleportions 3 are held in the usual manner on the knocking over bits 6,they will be widened. To avoid this widening, it is proposed to provideabove the bits 6 and in front of the needles of the bar 5 which hold theinitial courses of the sole portions 3 the strippers 8, III which on theoutside hold the meshes in position on the bits 6. Toward the inside,the strippers 9, III are upwardly directed in oblique manner, so thatthe meshes of the initial edges of the sole portions 3 located here cancooperate in the ascending and descending motion of the needles. Duringworking of the heel portions 4 the strippers -9, 10 are moved intogether with the members I of, the sinker head with the result thatalways only those meshes of the sole portions 3 are held on the bits 6which have to be knocked over. Seen from above, the two strippers 9, I0are arranged one after another so as to be able to overlap when themembers I are put back.

I claim:

Method of working the heel portions separately onto the high heelportions of a stocking produced in one operation on a flat knittingframe without the heel portions, consisting in separating the high heeland sole portions, transferring the sole portions to the machine workingon the heel portions inside near the high heel portions to connect thesole portions with the inner edges of the heel portions and hanging theheel portions during their production in their entirety continuallyinwardly by means of narrowers to place the meshes of their inner edgesgradually on the needles holding the sole portions, which are thenknocked over also.
